30 minutes? I don't have exact numbers, but I know ours is under 10 minutes and IMO that is not optimized at all. Maybe 30 minutes is okay for a very large project, but for most applications that seems quite high to me.

Our pipeline runs in Jenkins and builds a docker image that runs composer installs, application copy, and that sort of thing. We also run phpunit, phpstan, phpmd, and phpcs in our pipeline. Finally the image gets pushed up to ECR.

I think that's all pretty standard stuff. TBH I'd like us to move to github actions and optimize for more staged builds in our docker images, but we have higher priorities at the moment.
